Tottenham boss Harry Redknapp believes Bobby Zamora's former clubs are regretting letting go the Fulham hitman.

Zamora failed to make the grade at Tottenham after moving from Brighton, where he had scored 70 goals in 117 games, for £1.5million in 2003.

Just seven months, seven starts and one league cup goal later, Zamora was used as a make-weight in the deal that took Jermain Defoe from West Ham to Tottenham.

Zamora began to fulfil his potential at Upton Park but Redknapp believes he has become "a different class" playing under Roy Hodgson at Fulham this season.

"He is a really good player. West Ham probably regret letting him go. Tottenham probably regret letting him go. He is really looking the part," said Redknapp.

"He shows well, holds the ball well and is full of confidence. He is looking a real top player. His all around game has improved, and everything has been clicking for him."

Zamora launched Fulham's stunning Europa League comeback against Juventus with the first goal at Craven Cottage last Thursday in front of England manager Fabio Capello.

"I think he has a realistic shout (of playing for England)," said Redknapp. "Fabio was at the Juventus game and he must have been impressed with his performance. He is in the frame. He is bang in form.

"Anything can happen between now and then. One or two injuries. He is certainly not doing himself any harm."
